Rental Boyfriend App & Website

I have the concept, branding, and wire-frames for an online “rental boyfriend” service and now need the product built simultaneously for web and mobile. The very first release focuses on one thing above all else: a rock-solid booking system that updates availability in real time, no matter whether the slot is taken from the website or the app. Users will browse listed companions, view a live calendar, reserve a timeslot, pay, and receive instant confirmation. That calendar must lock the slot the moment payment clears and reflect the change on every device within seconds to eliminate double-bookings. Profile pages or in-app chat can wait for a later phase; the streamlined booking flow is the only must-have feature for this build. You’ll work with the assets I provide—UI kit, AWS account, and basic ERD—and deliver clean, well-documented code so my in-house team can extend it later. Deliverables • Responsive website wired to a shared back-end • iOS and Android app (React Native, Flutter, or similar) using the same API • Real-time booking engine with an admin override panel • Deployment scripts and technical documentation Acceptance Criteria • A booking made on one platform updates the other in under two seconds • No double bookings during load testing • Source code and documentation delivered in a private repo, ready for hand-off
